I unfortunately do not know alot about Hebdomas Pocket Watches. I don’t know how to tell what year this is. I also don’t know what the mark inside case means as far as what type of metal case is. What I do know is I have never seen a 24 hour dial on a Hebdomas… I also know that this particular one runs for a full 8 days and keeps excellent time! The hands have wear but are very cool looking! The crystal is clear. Feel free to ask me any questions and I will try my best to answer. Thank you for checking out my listing. The item “Hebdomas RARE 24 Hour!
